To all whom it may concern:

Be it known that we, CHARLES RIsAoHnn and PAUL ALBERT Hnennr, citizens of the ing is a specification.

This invention relates to improvements in devices for distributing regularly and. at several points small quantities of liquid, and the object of the invention. is to so construct a device of this character that it will overcome the dilliculties met with in endeavoring to obtain an absolute regularity in the delivery through several inlets supplied from the same source, and especially when Slif'll outlets are only to allow the passage of a very sinall'amount of liquid and when they are relatively far from one another; and will also obviate the "further dilliculty met with after havingestablished a uniform delivery through such inlets for a certain amount of the total delivery, such diliiculty being represented by the fact that generally such uniform delivery no longer sul sists onthe total deliverybeing increased or decreased. i

The device according to this invention consists of a tube connected with the source of the supply of liquid and on which are branched lateral ajutages orspouts, in combination with a, porous or fibrous material,

such as wicks, which fill the bore of the tube and spouts. The phenomena of capillarity resulting from the fibrous nature of the filling having the effect of regulating the delivery of all the spouts even when the spouts are spaced and numerous, or the tube is a long one on that accounna'nd such regularity subsists irrespective of the total delivery, even when the latter is a small one, or only a few drops per minute for a set of ten spouts, for instance. In order to secure a constant total delivery with such a device, it is expedient to maintain a constant pressure of the liquid supplied by the. source employed, which is generally a reservoir. It is advantageous, in order to be able to regu' late the pressure and hence the supply at will, to compress the air above the l quid in the reservoir and in keeping the pressure of such air constant by any suitable means, for instance by forcing the air continuously into a reservoir provided With a suitably charged For instance,

Improvements in Liquid smaller wicks 6 discharge valve. Such a distributing device can be used for distributing any sort of liq 1nd and can be'applied in many'industries. we Willdeseribe its application to the sprinkling of petroleum on the cylinders used in printing establishments; n such case, the petroleum is distributed in drops on thewhole surface of a felt roller turning against the surface of a cylinder of a printing machine. a

Such embodiment of this invention is ,shown as a whole diagrammatically in Figure 1 of accompanying drawings, in which Figs. 2 and 3 are, respectively, a transverse section of the distributing tub.:;. on a larger scale, and a longitudinal section. of the distributing tube as applied to'the sprinkling of petroleum of the second cylinder to a flat or what is called a double or withdrawal printing machine.

In the drawings, 1 designates a. distributing tube provided with lateral ajutages or spouts 2 and connected by a'pipe 3' with a reservoir 4- for the liquid. According to this invention, the bore of tube 1 is filled by a large wick 5 extending from one end to the other and the spouts 2 are provided with which extend to th'e interior of the main Wick 5.

Fig. 2 shows that an opening 7, closed by a threaded plug 8, is located in front of each ajutage 2; such opening serves for the purpose of inserting the wick 6 through the wick 5 and the ajutage 2, for instance b means of a hook passed previously througli the latter, through the wick 6 and the opening 7. I Fig. 1 shows an air pump 9 located at the center of the reservoir 4- and forcing the air above the liquid through an opening 10pm \jided with a retaining flap valve 11. The

pump operates continuously so long as the the delivery of the same which is proportional to the; said pressure. 13 designates a.

funnel for the supply of the liquid to. the reservoir 4 and which is provided with a stop-cock 14. At the outlet of the reservoir there is arranged a small filter preferably constituted by a hollow body 21 of porous earthenware, preventing the least impurity from being supplied to the distributing device ahd permitting the supply of the liquid proportionally to the pressure maintained m supplying the liquid to the same at severalthe reservoir.

In the application shown in Fig. 3, the distributing tube 1 extends from the interior of a hollow roller 15 the perforated surface of which is surrounded by a felt sheath 16 serving to allot and deposit the petroleum uniformly on the cylinder 17 in contact with which it revolves. Gear wheels 18 and 19 insure the-equality of the circumferential speedsof the cylinder and felt, and rollers 20 running on the latter limit the approachment of the parts in an invariable manner.

The petroleum 1s supplied from a reservoir kept under pressure by means of an' airpump, as hereinbefore' described, the said air-pump being.driven by any suitableoperating member of the printing machine, so that it will onlyoperate when the latter is running. By distributing the petroleum within the felted roller, there is the advantage ofkeeping the"'i'nass of, felt always clean, the impurities depositedon its outer surface being continuously expelled outwardly by the liquid coming in. Furtheri more, the device is very. compact.

The inventioncomprises any application of the said device to the allotment of liquid, involving a perforated and felted roller which revolves around a tube or .hollowaxle points of its length-regardless of the fitting of such tube and of the members distributing the liquid in the roller.
